Memory configuration and timing
The CY7C1367A-150AJC: 9Mbit synchronous SRAM organized as 512K x 18 bits — the 18-bit word width suits systems needing parity or ECC alongside the data bus without an extra chip. Rated for a 150 MHz clock with a 3.5 ns access time. The 3.5 ns access is the time from the clock edge to valid data on the outputs; at 150 MHz the cycle time is 6.67 ns, so the access time consumes just over half the cycle, leaving margin for board trace delay and input setup.
Commercial temperature range (0 °C to 70 °C) limits this part to indoor, controlled environments. Not rated for industrial or automotive ambient swings.
